Rubbing alcohol won't harm most plastics, but is usually too dilute (~70%) to be really effective at removing ink. I think that the plastic in CDs and DVDs is polycarbonate. Methanol will remove sharpie ink without harming the plastic. If you can't find it, denatured alcohol (Ethanol with some methanol added to discourage drinking it), which is available at hardware stores, would probably do it as well as, perhaps with a bit more elbow grease. Methylene chloride (paint remover) will dissolve polycarbonate, so don't use any solvents that contain it. -Chris ------------------------------------------------------------------------ | Christopher Judd, Ph.
